Is artist conk (fungus) dangerous

I have artist conk growh on my euclayptus tree stump. They look quite pretty so I have allowed it to grow for 2 months now. However, it seems to be starting to affect the honeysuckle plant that is growing around the stump.

Will it eventually affect and kill my neighbouring crooked willow and yew trees? If it is dangerous, how do I get rid of it without having to uproot the big stump?
